" PROCESS or MANUFACTURING LIQUID FUEL.

Ho Drawing.

To all whom it may concern."

Be it-known that I, JOSEPH BLACK, a citizen of the United States, residing at Los Angeles, in the county of Los Angele and State of California, have invented .certain new and useful Improvements in Processes of Manufacturing Liquid. Fuel, of which the following is aspecification.

This invention relates to a'process of manufacturing liquid fuel and the products derived therefrom, and has for its general object to provide, in a manner as hereinafter set forth, a liquid fuel for use in internal combustion engines or for any purposes for which the fuel is found applicable, which while capable of production at a cost below that of the well known gasoline of commerce, will be more efiicient than" the latter in the matter of power development, mileage per gallon, reducing carbo nization to an absolute minimum to assure constant free running of an engine, and ease in starting power in cold weather, and the foregoing several advantages are accom- 'plished by the use of\a liquid fuel manufactured in aocordancewith the process forming the subject matter of my invention.

In the production of a liquid fuel, in accordance with this invention, I employ a base of crude petroleum and raw coal oil,

7 or what is known to the trade as untreated coal oil. The crude petroleum and raw coal oil in the desired quantities are mixed together in a suitable still and to such mixture is added in the desired proportions, acetone, benzole, salsoda and wood or denatured alcohol. The composition as stated is then subjected to the action .of compresed cold air to. provide for a thorough agitationto obtain the complete admixing of the several constituents of the composition. After the agitation, the composition is submitted to heat and brought to a temperature of one hundred twenty degrees Fahr., and afterthe composition has reached the temperature referred to, it is subjected to the action ofv dry steam to what may be termed preserve the acetone, benzole, salsoda and alcohol so they will perform.their function in the ultimate product, or in other words dry steam 'is applied to prevent the burning up of the acetone, benzole, salsoda and alcohol.

Application filed September 27, 1923. Serial ll'o. 665,183.

temperature of the composition in the still I has reached four hundred twenty degrees F ahr., and by this time the come-over'or run discharged into the tank will reach one hundred gallons and'an endpoint-of 437, as is required. When the composition in the still is at four hundred twenty degrees Fahr., the'come-over or run is then shut off to the tank and conducted to a secondary .tank, and the supply to the latter will amount to seventy-three gallons of fortyfive proof gravity with an end point of 480. The composition within the still, as the come-over'or run is supplied to the second"- ary tank, reaches four hundred eighty degrees Fahr., and will stand as such. After the secondary tank has been shut off to the still, the residuum of the composition remaining,. amounting to approximately twenty-five gallons of thirty-two proof gliavity, is removed and utilized for stove o1 The liquid fuel contained in the secondary tank, has combined therewith, in suitable proportions, acetone, benzole, alcohol and easing head gas, and the mixture is thoroughly a itated for a predetermined period,

and whic will raise the gravity of the. fuel to sixty proof, making it an unusually satisfactor 470 and 480.

As an example of the proportions of the several constituents from which a liquid fuel, in accordance with thisinvention, is manufactured, I employ one hundred gallons of crude petroleum, one hundred gal-' lons of raw coal oil, or what is known to the trade as untreated coal oil, two gallons of acetone, two gallons of benzole, ten poundsof salsoda and one-half allon of fuel having an end point between wood or denatured alcohol. The proportions, by way of example, of acetone, benzole and alcohol which are admixed with the fuel in the secondary tank, are as follows 14: ounces acetone, 14: ounces benzole, 12 ounces alcohol.

The several constituents added to the petroleum and coal oil act to prevent carbonization, to lower the ignition point or flashing point, providing for the thorough combining of the crude petroleum and coal oil, or rather to form a homogeneous and permanent mixture, as well as acting as a carrying or mixing medium to provide a permanent and homogeneous mixture.

lhe acetone employed in the fuel in the secondary tank acts as a binder between the coal oil and easing head gas, or in other words, prevents the separation of coal oil from the casing head gas.

What I claim is 1-- 1. A process of manufacturing a liquid fuel comprising the distilling of a composition consisting of crude petroleum untreated coal oil in approximately equal volumes combined with a mixture consisting of acetone in the approximate proportion of onefiftieth of the volume of petroleum, benzole in the approximate proportion of onefiftieth of the volume of the petroleum, salsoda in the approximate proportion of one-eightieth of the volume of the pe troleum, and alcohol in the ap roximate proportion of one two-hundredt of the volume of the petroleum to a temperature of one hundred twenty degrees Fahr. to start a come-over or run, then collecting in a receiver the come-over or run until the temperature of the composition reaches four hundred twenty degrees Fahn, thereby providing a liquid fuel of fifty-eight proof gravity and 437 end point, and then collecting in an independent receiver the come-over or run until the composition reaches a temperature of four hundred eighty degrees, thereby providing a liquid fuel of forty-five proof gravity and end point of 480. y

2. A process of manufacturing a liquid fuel comprising the distilling of a composition consisting of crude petroleum untreated coal oil in approximately equal volumes combined with a mixture'consisting of acenaeogsee tone in the approximate proportion of onefiftieth of the volume of petroleum, benzole in the approximate proportion of onefiftieth of the volume of the petroleum,

salsoda in the approximate proportion of.

one-eightieth of the volume of the petroleum, and alcohol in the approximate proportion of one two-hundredth of the vol ume of the petroleum to a temperature of one hundred twenty degrees Fahr. to start a come-over or run, then collecting in a receiver the come-over or run until the temperature of the composition reaches four hundred twenty degrees Fahrz, thereby providing a liquid fuel of fifty-eight proof gravity and 437 end point, then collecting in an independent receiver. the come-over or run until the composition reaches a temperature of four hundred eighty degrees, thereby providing a liquid fuel of forty-five proof gravity and end point of 480, and then raising to sixty proof gravity the liquid fuel of forty-five proof rravity by combining therewith casing head gas, acetone, benzole andalcohol.

3. A liquid fuel obtained by dry steam distillation of approximately equal volumes of each of crude petroleum and raw coal oil distilling over between approximately 120 degrees Fahr, and 420 degrees Fahn, and containing approximately 5% of a mixture of approximately equal parts of each of acetone and benzole and a smaller proportion of alcohol, and water obtained from the dry steam.

4. A liquid fuel obtained by dry steam distillation of approximately equal volumes of each of crude petroleum and raw. coal oil distilling over between 420 degrees Fahr, and 480 degrees Fahn, and water obtained from the dry" steam.

5. A liquid fuel obtained by dry steam distillation of approximately equal volumes of each of crude petroleum and raw coal oil distilling over between 420 degrees Fahn, and'480 degrees Fahn, and water obtained from the dry steam, combined with casing head gas and a mixture of approximately equal parts of alcohol, acetone and benzole, and water obtained from the dry steam.
